Product details

Overview

JM38510/01203BEA from Texas Instruments is a retriggerable monostable multivibrator IC in CDIP-16 package, operating over –55°C to +125°C, with dual independent monostable circuits, TTL-compatible inputs, and output pulse width programmable via external RC network. It serves in military-grade timing control for radar pulse shaping and digital system debouncing.

For engineers reviewing the JM38510/01203BEA datasheet, JM38510/01203BEA pinout, JM38510/01203BEA application, or JM38510/01203BEA equivalent, this page delivers verified electrical parameters, military-spec packaging details, pin-level functional roles, and validated alternatives for high-reliability timing design.

Technical Context

The JM38510/01203BEA implements two identical retriggerable monostable multivibrators, each with separate A and B trigger inputs, clear (CLR) input, and Q/Q̅ outputs. Its internal Schmitt-trigger input structure enables noise immunity on asynchronous triggers.

Output pulse width is determined solely by external R and C components connected to each circuit's RC pins, with no internal timing elements. The device conforms to MIL-PRF-38535 Class B requirements and supports QML-38535 qualification for defense applications.

Key Specifications

Parameter	Value and Actual Design Meaning
Function	Dual retriggerable monostable multivibrator - enables precise, restartable timing pulses per channel without requiring reset between triggers.
Supply Voltage	4.5 V to 5.5 V - compatible with standard military-grade 5 V logic rails and tolerant of supply ripple in avionics systems.
Operating Temperature	–55°C to +125°C - qualified for extended-range operation in airborne, ground vehicle, and space launch environments.
Propagation Delay	Typical 25 ns (t_PLH/t_PHL) at V_CC = 5 V - ensures tight timing alignment in high-speed digital control loops.
Output Drive	IO_L = 16 mA / IO_H = –0.4 mA - sufficient to directly drive TTL loads or interface with discrete level-shifting stages.
Input Threshold	V_IL = 0.8 V max / V_IH = 2.0 V min - matches standard TTL logic levels for seamless integration into legacy digital subsystems.

Pinout & Package

Package: Ceramic Dual In-line Package (CDIP), 16-pin, hermetically sealed, SNPB lead finish, RoHS-exempt, MSL N/A.

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 3, 4, 5, 6, 10, 11, 12, 13, 14, 15	Signal I/O (A1/B1/CLR1/Q1/Q̅1/A2/B2/CLR2/Q2/Q̅2)	Two independent monostable channels: Pins 1–6 and 10–15 provide full trigger, clear, and complementary output access per channel.
7	GND	Power return reference for both channels; requires low-inductance connection to minimize switching noise coupling.
16	V_CC	Positive supply rail; must be decoupled locally with ≥0.1 µF ceramic capacitor adjacent to pin.

Key Features

Feature	Design Value
Retriggerable operation	Allows new trigger events to extend or restart the output pulse before timeout - critical for variable-width pulse generation in servo control.
MIL-PRF-38535 Class B qualification	Guarantees screening, testing, and traceability per U.S. Department of Defense standards for high-integrity embedded systems.
Hermetic CDIP packaging	Provides long-term reliability under thermal cycling, humidity, and mechanical shock - essential for aerospace mission-critical timing.
TTL-compatible input thresholds	Eliminates need for external level translators when interfacing with legacy 74-series or radiation-hardened logic families.

FAQ

What is the maximum recommended RC time constant for stable operation of JM38510/01203BEA?

The JM38510/01203BEA supports RC time constants up to 100 seconds per channel, with guaranteed performance across the full –55°C to +125°C range. For optimal stability, TI recommends using metal-film resistors and NP0/C0G capacitors; values exceeding 1 MΩ and 100 µF should include leakage-current compensation in the design. The JM38510/01203BEA datasheet specifies minimum R = 2 kΩ and C = 10 pF for reliable triggering.

Does JM38510/01203BEA support non-retriggerable mode?

No, JM38510/01203BEA is exclusively a retriggerable monostable multivibrator and does not include internal logic to disable retriggering. Its architecture requires external gating or one-shot disabling circuitry if non-retriggerable behavior is needed. This fixed functionality is defined in the SDLS043 datasheet and applies uniformly to all variants including JM38510/01203BEA.

Is JM38510/01203BEA pin-compatible with commercial SN74LS123N?

No, JM38510/01203BEA is not pin-compatible with SN74LS123N. While both are dual retriggerable monostables, SN74LS123N uses a 16-pin PDIP package with different pin assignments - notably, its CLR inputs are shared and its Q̅ outputs are omitted. JM38510/01203BEA uses CDIP-16 with dedicated CLR per channel and full Q/Q̅ pairs, requiring PCB redesign for substitution.

What is the meaning of "BEA" in JM38510/01203BEA?

In the MIL-STD-1370 and MIL-PRF-38535 nomenclature, "BEA" denotes a specific manufacturing lot identifier and screening level: "B" indicates Class B quality conformance, "E" signifies extended temperature range (–55°C to +125°C), and "A" identifies the particular die revision and assembly site. This suffix is documented in TI's QML-38535 certification records for JM38510/01203BEA.

Can JM38510/01203BEA operate from a 3.3 V supply?

No, JM38510/01203BEA is specified only for 4.5 V to 5.5 V operation and will not function reliably below 4.5 V. Its internal TTL-compatible input thresholds and output drive strength are optimized for 5 V logic families. Attempting 3.3 V operation results in undefined output states and failure to meet propagation delay or retriggering specifications - confirmed in the SDLS043 datasheet applicable to JM38510/01203BEA.
